摘要:
A hybrid vehicle and method of control are disclosed wherein the ratio of engine speed to vehicle speed varies continuously in some operating modes and is controlled to simulate a discrete ratio transmission in other operating modes. The disclosure specifies the method of controlling the engine speed and the combined output torque of the engine and at least one traction motor in each of the operating modes. Transitions among operating modes occur in response to driver movement of a shift lever, driver operation of shift selectors, and changes in vehicle speed.

An active damping system provides a torque adjustment command that is combined with the raw motor torque command of a vehicle to compensate for oscillations and vibrations in the driveline of a hybrid vehicle. Active damping may be provided by a derivative controller or by a lead-lag compensation between initiation of clutch engagement and full clutch engagement. Active damping is terminated upon full clutch engagement.

Illuminator module comprising VCSEL arrays with planar electrical contacts, readily adaptable for surface mounting, is provided. Monolithic VCSEL arrays are configured in array patterns on two and three-dimensional surfaces. Illuminator modules are easily expandable by increasing the array size or by modularly arranging more arrays with or without a transparent substrate. Different shapes of illuminator modules may be configured by tiling array modules monolithically on a common substrate, or by tiling small modules. The surface mountable illuminator modules are easily assembled on a thermally conductive surface that may be air or liquid cooled for efficient heat dissipation. Array modules may be integrated with other electronic circuits such as current drivers, sensors, controllers, processors, etc. on a common platform, for example, a single or multiple layer printed circuit boards (PCB) to assemble illumination systems for different applications including a gesture recognition apparatus and a battery operated portable illuminator devices.

An optical compound sheet for a backlight module includes a base layer formed of a transparent material, a plurality of structured patterns formed on the base layer at a predetermined interval, a light-condensing layer which includes a surface coating including nano-particles distributed on the surface of the structured patterns at the thickness of 0.01 μm to 1 μm, and an anti-scratching layer which is coated under the base layer at the thickness of 0.1 μm to 3 μm by using the UV-curable bond containing nano-particles. While improving the anti-scratching performance by using the surface coating and the anti-scratching layer containing the nano-particles, the wet-out and Moire phenomena are greatly reduced by the finely separate coating of the nano-particles, thereby achieving both the light-condensing function and light-diffusing function.

The present disclosure provides a method and a system for accessing a microblog and a method and a system for sending a picture on a microblog website, and relates to the field of computer technology. The present disclosure includes: prestoring an original picture and a text at a server, and correspondingly storing a thumbnail picture corresponding to the original picture; the server sends the text and the thumbnail picture to the mobile terminal when the mobile terminal sends a request to the server to access the microblog; the server sends the original picture to the mobile terminal when the mobile terminal sends an original picture downloading request to the server to request for obtaining the original picture corresponding to the thumbnail picture. In the embodiments of the present disclosure, a text and a picture are stored separately at a server, and the picture may comprise an original picture and a thumbnail picture. In this way, when a mobile terminal accesses a microblog at the server, the thumbnail picture may be sent to the mobile terminal; and the original picture corresponding to the thumbnail picture is sent to the mobile terminal upon a request from the mobile terminal, so as to reduce the amount of data transmission.

A method and system for limiting a fast transient in an engine in a hybrid vehicle is provided. The predicted fuel loss percentage is calculated from an inferred air-fuel ratio (inferred lambda). The rate limit term is calculated from a measured air-fuel ratio (measured lambda) and an engine torque command change rate. The predicted fuel loss percentage and the rate limit term are inputs into a calibration table to determine an engine power rate limit and an engine torque rate limit. An engine torque command is limited using the engine torque rate limit to control a fast engine torque transient for an engine. An engine power command is limited using the engine power rate limit to control the fast engine power transient for the engine.

A powertrain for a hybrid electric vehicle (HEV) such as a plug-in hybrid electric vehicle (PHEV) includes an engine, a fuel tank, a battery, and a controller. The controller is configured to determine a distance to empty value as a sum of fuel in the fuel tank and a battery equivalent amount of fuel, the sum multiplied by an average fuel economy of the PHEV based on a driving condition of the vehicle.
